After debuting at Sundance to great reviews, Maya Forbes' feature debut, Infinitely Polar Bear,has been bought by Sony Picture Classics.

Starring Mark Ruffalo and Zoe Saldana, the heart-tugging drama follows the parental travails of a bi-polar father who takes care of his two young daughters while their mother attends business school to support the family.

In an interview with Women and Hollywood, Forbes explained, "I wrote a script based on my childhood, growing up with a manic-depressive father and a mother who had to make some very hard choices. I feel lots of families face the many issues I explore in the film. I wanted [the film] tto be funny and heartbreaking and visceral and entertaining."
